media: staging/intel-ipu3: make imgu use fixed running mode
Currently, the imgu running mode need user to set by v4l2 ctrl. However, imgu only support 2 pipes and 2 operation modes - video and still. This patch make the first imgu subdev running as video and second one running as still, it will make the user understand easily, it can also cover current camera use cases requirement. The running mode is set during subdev registering, no race-condition after change, so it is safe to change the mode data type to integer.
